Ok, if you didnt read my problem, i'll put it again. Limewire never connects or downloads a single thing. That's basically it.

I have
-Wndows XP Home Edition
-I have windows firewall only, and its disabled
-I have 512 mb of ram.
-My hard disk space available is 83gb
-My connection type is cable modem
-My modem is Motorola USB Modem, not sure about my router
-im connecting from home
-i have limewire PRO 4.10
-My ISP is called icecelular and they dont block Gnutella
-I have emule installed and i never use it when i try to run limewire, but this one does'nt work either.
-I made the test you gave me and it didnt work.

So, after i placed all this things in a new thread i hope this time i get the help i need.

Sometimes you have to be patient. We're all volunteers here & it takes time to answer so many questions.

You said you made the test. Was it this port test?

If that's the test that didn't work, something is blocking LW's default port. Do you see the firewall icon (brick wall in front of the blue earth)?

Have you been through this sticky?
Connection problems? Check here first!
Since emule doesn't work either, I'd be suspicious of your ISP. Do you know anyone who has the same ISP & uses p2p successfully? It would help to know the brand & model numbers of both your modem and router.

Have you tried changing to a higher port? There are instructions & info here
